The following signal and display functions are available in conjunction with motor pro-
tection:
Parameter Signal and display function
P006/P007 Motor utilization1/2
(→2192)
Motor utilization for parameter set1/2
P832 Response to "Motor overload"
(→2225)
Error response of the device when the motor
utilization reaches the value 110%.
Factory setting: Emergency stop/malfunction.
The following parameters must be set:
Parameter Setting/meaning
P341/P343 Type of cooling1/2
(→2207)
Self-cooling or external cooling
Binary output programmed to the re-
sponse: "/Motor utilization1/2"
Prewarning if motor utilization exceeds a value
of 100%. In this case, the programmed binary
output is set to zero (0V).
INFORMATION
Deactivating the device (supply system and external DC 24 V supply) always sets the
motor utilization to zero. After reactivation, already existing motor heating is not con-
sidered.
The motor protection function processes the utilization of the connected motors separ-
ately for both parameter sets. The motor protection function may not be used in the
following cases:
• if only one motor is permanently connected to the device and the "parameter set
changeover" function is only used for control technology purposes.
• in the case of group drives. In this case, not every individual motor can be reliably
protected.
Setting: One servomotor
• Motor without KTY temperature sensor:
The power section "PFA-..." calculates the motor utilization based on the nominal
motor current. The aim is to determine after only a few cycles or during startup
whether the drive will switch off due to an overload, with the error message
"A1.F31" (TF/TH trip). In order to determine the capacity utilization at which the
connected motor drives the machine cycle as precisely as possible, the duration of
the machine cycle must be entered.
This setting is only possible for parameter set 1.
The following signal and display functions are available in conjunction with motor pro-
tection:
Parameter Signal and display function
P006 Motor utilization1 (→2192)
Motor utilization for parameter set1. Valid after
10 to 20 cycles or after about 2s and can be
evaluated by a PLC.
P007 Motor utilization 2 (→2192) No function in this setting
